A-p-plieationnled November 21, 1927. Serial No. 234,849;

This invention relates to floor joiners which are assembled and adapted to be shipped'to the job ready to be installed in the building, to cover the joints of abutting floors without the usual tasks of measuring and .fitting to make the parts properly cooperate.

Oney object of this invention is to provide a ioorjoiner having a bar to which is securely attached clamps having flanges for securing the same in position, and a binding plate adjustably carried by said bar.

Another object is the provision of a floor joiner having an lanchoring member by means of which the plate may be adjusted to properly fit the floor as it shrinks or wears, thus providing a permanently tight and attractive joiner for new or old fioors made of any kind of material.

A Afurther object of this invention is the contemplation of a floor joiner having a temporary Spacing washer between the plate and the bar to insure a tightening space when the j'oineris installed, and the washer removed.

Still vfurther objects of this invention' are ease of installation, ease of adjustment, adaptability to varying conditions, and durability of construction. f

With these general objects in view, as well as minor objects which will appear in` the course of the detailed specification, the invention will now bedescribed with reference to the accompan ing drawing, illustrating a construction -em odying the4 improvements of this invention. l

. In the drawing- Figure 1, is a perspective view ofa floor joiner embodying this invention.

Y. Fig. 2, isa perspective view of one of clamps detached.

the

Fig. 5, is a cross-section of the floor joiner'y shown in operative position' in a floor construction, and

Fig. 6, is a tion taken on line fragmentary longitudinal A sec- VI-VI of Fig. 3.

Similar reference characters-designate like parts throughout the 'several views and the numeral 7 designates aber made of wood o r nut. vided with oppositely disposed flanges 13,

temporary spacing washposition, and witht-he bar' horizontal section preferably vpunched from,

said clamp.v These flanges are adapted to engage slots 10 which are formed in the nuts 11. When the clamp 8 has been properly formed, and the nut pressed into position, asshown in Figs. 5 and 6, Ia hole 12 in the upper surface of the clamp 8 will register with the threaded opening in the The lower portion of clamp 8 is prohaving perforations 14, for the reception of nails by means of which the clamp may be securely attached to the nailing block 15, as shown in Fig. 5. Positioned between flanges 13 and integral with clamp 8, are inwardly turned flanges 16 which serve to encase the bar 7, and have nail holes 1 7 which may be used vfor 'the reception of nails to secure the lower portion of clamp 8 to bar 7 to prevent spreading. The anges 16 are of Such length that should t-he clamps 8 be used without the bar 7 or should the wood har decayso that they no longer serve as a filler for the clamp, then the abutting adjacent ends of' theJ flanges will serve to prevent the crushingv in of the clamp. As clearly shown' in Figs. 5 and 6, it will be' noted that the bar 7 is provided withgrooves 18, ofv sullicient dimension to receive nuts 11,

thus making it possible to properl space and securely hold the clamps. in lpre etermined relative' positions on the bar. j, i

Positioned above bar 6, and

washers 19, is the joiner plat-e 20, having a Series of count-ersunk holes 21 for the recep- .tion of flat-headed screws 22. This-joining plate '20 'may be of anyv standard threshold -plate shape, or when it is desired to maintain a smooth level surface where the floors are joined, a. flat 'plate may be used.

f When it is' of this type, construction v the two floors and nailing blocks are insert*- a trough is formed in the floor v l spaced apart 'therefrom by means of temporary spacing desiredto install a floor joiner v between the adjacent',V edges of ed therein, so that when the assembled floor binder with the temporary spacing washers in position is mounted thereon, the under surface of the binding plate will be approximately at the -level of the floor surfaces. The clamp members are then nailed to the nailing block. The binding plate is removed, and concrete is then poured around the nailing block and bar to a depth suflicient to securely anchor the binding bar and clamp securely in a fixed position. The temporary spacing washers 19 are removed, and t'lie'binding plate 2O is securely attached to the anchored clamp by means of screws 22.

Should the floor shrink or wear and the binder plate become loose, the screws may be turned to again draw it to a snug lit and due to .the fact that the clamp, binder plate, bolt and nut are preferably made ot rust proof material, the joiner will always be in condition to be adjusted, and will last much longerthan the ordinary type.l

l I do not limit this invention to the structure shown and described, as many modifications may be made within the scope of the appended claims without departing from the spirit thereof. v

lVhat is claimed as new and desired to be secured by Letters Patent is:

. 1. As a new article of manufacture, a Hoor joiner comprising a bar, a plurality of spaced apart clamps securely carried by said bar, oppositely disposed flanges extending outwardly from said clamps, a binding plate lcarried by said bar and means for adjustably connecting said bar and binding plate.

2. As 'a new article of manufacture, a floorjoiner comprising aA rectangular bar, a plurality of equally spaced apart clamps securely carried by said bar, oppositely dis-v posed flanges extending outwardly from each of said clamps, a binding plate carried by said bar, and means for adjustably connecting said bar andbinding plate.

3. As a new article of manufacture, a floor joiner comprising a bar, a plurality of spaced apart clamps encompassing said bar, means for securing said clamps against longitudinal movement on said bar, oppositely -disposed anges extendingoutwardly from the lower portion of each of said clamps, a binding plate-carried by saidA clamps and of spaced apart clamps securely attached-to a said bar, oppositely disposed flanges extending outwardly from the lower edge of each of said clamps, a nut carried by each of said clamps and positioned in' a notch in said-bar, a binding platevcarried by said bar and a bolt' for adjustably connecting said bar and binding plate. s Y

5. As a new article of manufacture, a lloor joiner comprising a rectangular bar having a plurality of notches in one edge thereof, a plurality of equally spaced apart clamps encompassing said bar, oppositely disposed flanges extending outwardly vfrom the lower edge of each of said clamps, a nut carried by each ot' said clamps and positioned inone of the notches in said' bar, a binding plate carried by said bar and separated therefrom by means of washers.

6. As a new article of manufacture, a floor joiner comprising a bar having aplurality of spaced apart notches in one edge thereof, spaced apart clamps encompassing -said bar and positioned over said notches, oppositely disposed flanges extending outwardly from each of said clamps, a nut carried 'Within each of said clamps, a binding plate positioned above said bar, and bolts to engage said plate and nuts to adjustably secure saidl plate to said clamps.

' 7. As a new article of manufacture, a lloor joiner comprising a rectangular bar having a series 'of equally spaced yapart notches in one edge thereof, a clamp encompassing said bar at each of said notches, and means for SAMUEL C. AVBREY.
